Having had a very quiet USB ground hum (Windows 11 / USB / DAC), I ordered one of these gadgets and the dang thing works. It does not inhibit the transfer of highest resolution audio files. Two things: I use a 5 volt power source for the HS01 and that is plugged into my power conditioner. They advised the power for the HS01 must not come from the computer.
